With this implantation I get kernel panic at Unresolved kernel trap(cpu 1): 0x400 - Inst access DAR=0x0000000002279000 PC=0x0000000000000000 Latest crash info for cpu 1: Exception state (sv=0x1DE5E500) PC=0x00000000; MSR=0x40009030; DAR=0x02279000; DSISR=0x40000000; LR=0x00288520; R1=0x0CD9B9F0; XCP=0x00000010 (0x400 - Inst access) Backtrace: Why I get kernel panic on this zombproc and why my driver jump to zombproc function from the driver thread?
